To all wwm t may concern.'

Be it known that l, FRA-Nn J. Ko'rzion, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Iliinois, have invented certain new and useful improvements in Automatic Machines for Making and Applying Metallic Binding Ciips to Webhing; and l do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification. l

rIhis invention relates to a novel and improved autoinatic machine for making and applying metallic binding clips to webbing, such as garter elastics and the like, and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

rihe object of the invention is to provide a machine which will automatically out, form and apply metal clips to webbing,the clip blanks heing cut from a continuous length or strip o metal which is automatically fed to the cutting, forming and applying head of the machine.

The various advantages of the invention will appear as l proceed W'ith niy specification.

The improved machine in its preferred form is actuated and operated in the ,maiiner of the famiiiar punch press wherein a reciprocating die member, operated hy a rotating member, is connected for each opy eration by the action of a foot treadle to a continuously rotating power memher.

Referring now to that embodiment of the invention iliustrated in the drawingsz-- .the bracket plate. Said casing contains the cutting, forming and applying members of the mechanism.

t the ieft hand side of the bracket plate is located the feeding mechanism 17, by which a continuous strip of thin metal is fed to the casing i6. Ahove the casing 16 is mounted the rotative actuating member 18, in this case a cam, which cam operates the several cutting, forming and applying members contained in the casing 1 6. Said cam is fined on a shaft i9, which is capable of connection with a continuously rotating power member hy means of a foot treadle, in a. weil known manner. Y

VReferring now to the casing 16 and to the parts Within the same: The casing consists of a channel piece 20 having a back plate 2l and side plates 22, 22 and of a face plate 23, which is attached to the front edges of the side plates 22. In the closure thus providedV are mounted three vertically reciprocahle memhers,-a die carrying mem ber 24, a forming member 25 and an indenting'or punching member 26. The die car- `rying member '24, as illustrated, is a channel member, similar in cross-section to the channel member of the casing in which it is mounted for guiding relation. 27 indicates the die itself, which is of rectangular, tubular form and is fixed in any convenient way to the bottom end of the member 24, with the opening throu h the die in alignment with the channel o the member 24.

The forming member 25 is a bar slidably mounted in the channel of the die carrying member 24 with a wedge shaped forming end 25 at its bottom, offset from the back wall of the channel of the die member 24, and extending down into the tubular die 27. The punching member 26 is also a rectangular bar slidably mounted in front of the forming member 25, between the sides of the channel of the die member 24,-said bar being let into a channel-like groove 28 formed in the rear side of the face plate 23. At the bottom end of the punching member are carried a plurality, in this case three, of hardened pins or points 29, said points being made integral with a plate 30 removably fixed to the bottom end of the punching member. As shown, (Fig. 14) the punching member is provided with a horizontal, recessed shoulder 31 against which the top end of the plate 30 is engaged,-said shoulder preventing shearing strain on the screws by which the point plate 30 is at tached to the punching member.

Above the punching member and in line therewith, a lug 32 is attached to the top end of the forming member 25 (see Fig. 3). An elongated recess 33 is provided in the punching member 26, with a threaded hole 34 at its bottom end. 35 indicates a rod located in the recess 33, with its bottom end threaded linto said hole 34 and its top end 36 reduced in diameter and extending through an aperture in the lug 32. A coiled spring 37 surrounding the rod 35, is interposed between the bottom of the recess 33 and the lug 32. shoulder at the point where the reduced end part of the rod 35 begins,said shoulder being located a short distance below the lug 32. The top end of the rod 35 is slotted to receive the end of a screw driver, so that said rod may be easily rotated' to screw it up or down in the hole 34 to ad'ust the position of the shoulder 38 with re erence to the lug 32, for a purpose presently to'be described.

The die, member 24 and the forming member 25 are operatively connected to the cam 18 and vare independently actuated thereby, while the punching member 26 is actuated by the forming member 25. 39 indicates a cam groove in the face of the cam 18 which includes an active portion 39, and

38 indicates an annular 40 indicates a roller engaged in said groove and mounted on a pin 41 extending rearwardly from the die member 24, at its top end. 42 indicates a second cam groove in the face of the cam 18, having an active portion 42a, in which operates a roller 43 mounted on a pin 44 extending from the rear face of the forming member 25, at its top end. The roller 43 is mounted eccentrically on the pin 44 which may be rotated for purposes of adjustment, being locked in adjusted position by means of a transverse pin 45 which engages a groove in the main pin 44.

In the casing 20, below the die carrying member 24, are provided two horizontally disposed female cutting and corrugating die plates 46-47 respectively, the one superposed upon the other. The top die plate 46 is provided with a die opening 48 with which the die 27 coacts to cut the clip blank from the stock strip, there being a shallow groove 49 in the top Surface of this plate, to guide the stock strip as it is fed to the same. In the corrugating die plate 47 is provided an opening 50, somewhat smaller than the opening` 48 in the plate above, the front and rear sides of said opening 50 being corrugated along their top edges as at 51. These two plates extend through the left hand side wall 22 of the casing (see Fig. 7) and are removably secured in the casing by a screw 52 (see Fig. 11), the said casin;r beine,r otherwise constructed to sustain said plates against the pressure imposed upon them.

The bottom end of the casing below the plates 46-47 is hollowed out to provide a. chamber in which is located a movable anvil block 55 in the form of a step-by-step rotating cylinder.

The anvil block 55 comprises a relatively short, horizontal cylinder, which is ixed to a. horizontal shaft 57 arranged parallel to the plane of the bracket plate 15. The cylinder is cut away on four sides to provide segmental recesses 58, each having a wide and a narrow side 58, 58" respectively. These recesses are closed at their ends by end plates 59, secured to the cylinder in any suitable manner. (See Figures 7 and 8.)

In each recess is provided a V-shaped forming pocket 58c adapted to receive the clip blank and, in cooperation with the forming member, to bend s aid blank into V-form. As shown said forming` pockets are rovided on one side by a fixed wing mem er part, the same being the narrow side 58b of the aforesaid recess 58 and by a swinging wing member or part 60. Said wing members receive andl form the blank between them in the one position of the anvil, and in the second or attaching position of the anvil the wing part 60 acts to fold and press the V-shaped clip blank upon the end of the webbing to which it is to be attached. Each swinging wing part has extensions or trunnions 61 parallel with the shaft 57, which bear in suitable holes in the end plates 59, with their axes in a line approximating the intersection line of the lanes of the twowing parts 60 and 58".

ach swinging Wing part also has end 'flanges 62 which engage the wider sides of the recesses 58 at their ends to form, when in one position, continuation of the surface of the cylinder 55. Between the end flanges 62- are provided teeth 63 separated from each other by spaces 64, the endmost teeth being made integral with the flanges 62. The width of thetV-shaped ocket provided by the wing parts 60 an 58 is restricted at the periphery of the cylinder by opposed shoulder flanges 65-66 on the outer edges of said wing parts respectively, behind Which the edges of the clip blank are engaged when the forming member has forced the clip blank into the said pocket. Said flanges overhang the pocket and prevent the blank from being accidentally dislodged therefrom.

'lhe rear face of the teeth are cam-shaped and include the convex and concave surfaces 67-67a respectively (see Fig. 5). rllhe cylinder also carries leaf springs 68 (see Fig. 13), which engage the ends of the flanges 62 of the swinging wing part and urge them outwardly so that the formed clip is yieldingly held in the forming pocket 58.

rlhe cylinder 55 is rotated a quarter of a revolution, step by step, by means of the following construction: The shaft 57, to which the cylinder is fixed, bears at one end (the right hand end) in the side walls 22-22 of the casing. (See Fig. 7.) rlhe other end of said shaft is reduced in diameter and bears in the bottom end of a forwardly offset lug 70 made integral with a block 70 on the front face of the bracket plate 15. (See Figs. 1 and 2.) Fixed to the shaft 57, next to the left hand side wall of the casing 16, isa locking disc 71 having arcuately spaced notches 72 in its periphery. (See Fig. 6.) Said disc has a hub 73 in which are provided laterally projecting ratchet teeth 74. Surrounding the shaft 57, between the lug 70 and the disc 71, is a tubular sleeve 75 in which is provided a spiral slot 76 (see Fig. 1) which extends arcuately about the sleeve through substantially 90. ln that end of the sleeve 75 facing the disc hub 73. is provided a spring pressed, longitudinally extending pin 7 5a, which coacts with the ratchet 74 so that when the sleeve is rotated a quarter of a revolution in one direction, in a manner to appear later, the pin will engage one tooth on the hub 73 and turn said hub and the shaft 57 one quarter of a revolution; upon a reverse rotation of the sleeve, said pin will click past said ratchet teeth. Associated with the disc 71 is a spring pressed' detent plate 77 (see Fig. 6) havingpa tooth 78 adapted to coact with the notches 72 in the disc 71 to lock said disc against rotation. This detent plate is carried on the bottom end of a vertically movablerod 79 which has sliding bearing in ears 80 at the rear of the left hand side wall 22 of the casing. Surrounding the rod 79 between the plate 77 and top ear 8O is an expansion coiled spring 81 which normally urges the rod downwardly. The top end of said rod 79 projects above the top bearing ear 80 so that it may be actuated in proper timed Irelation to u'nlock the disc 71 liust before it is to be rotated, by means of its hub and the sleeve 75, and to again lock the same against a reverse movement.

In the top surface of the lug 70 is provided a shallow groove 82 (see Fig. 2) eX- tending parallel with and in the vertical plane of the axis of the shaft 57. This groove receives and guides the stock strip 83 from which the clip blanks are cut and formed. 0n the front face of the block 70a is provided a screw stud 84 upon which is eccentrically mounted a strip gripping roller 85, there being a coiled spring 86 (see Fig.

v2) on the stud and engaging the roller in such a manner as to normally urge it toward the stock strip in the groove 82. This roller permits the stock strip to be moved or fed in one direction only (toward the right in Fig. 1) and automatically acts to grip and lock the stock strip against any movement in the opposite direction.

Fixed in the block 70a are two vertically spaced horizontal rods 87 which extend toward the head 16. Slidable on said rods is a feed block 88, said block having a shallow groove 88a to receive the stock strip. 0n the front face of the block is a gripping roller 89 similar in construction and operation to the roller before mentioned. Un the right hand face of the feed block is provided a guide 90 which embraces substantially half the width of the stock strip, and on the head 16 is a similar guide 91 which embraces substantially the other half of the width of said strip, the said guides coacting to prevent buckling of the stock strip as it is fed into the head. 0n the bottom of the block 88 is provided a screw 92, the head of which extends into the slot 76 in the sleeve 75. On the rear face of the b-lock 88 is provided a roller 93 which is engaged by the forked bottom end 94 of one arm of a bell crank lever 95.

The lever 95 is pivoted between its ends on a forwardly projecting stud 96 secured in the bracket plate 15. The other arm 97 of said lever 95 carries a roller 98 at its top end, which roller is arranged in the plane of an active cam projection 99 on the periphery of the cam 18. A coiled spring 96a (shown in dotted lines in Fig. 1) is fixed at its ends to the bracket 15 and bell crank lever 95 respectively in such manner as to normally urge the top arm 97 toward the cam 18 and to move the feed block 88 toward the block 7 0 on the bracket. Threaded through the block a in a plane parallel with and midway between the guide rods 87 is a setscrew 100 which acts as a stop against which the block 88 engages. As this set-screw limits the movement of the feed block 88 in one direction, it determines the length of feeding movement of said block and may be adjusted in or out, to feed just the proper length of stock strip to make one clip blank. Thus no stock is wasted between each clip blank cut and formed from the strip. .After the screw 100 has been once adjusted 1t may be locked by a lock nut 101.

0n the rear face of the bracket plate 15 above and to one side of the stud 96 is a second stud 102, upon which is pivoted at its middle a lever 103 shown in dotted lines in Fig. 1. The top end of said lever carr1es a forwardly extending roller 104 wh1ch projects through a notch 15L in the bracket plate so as to be engaged by a second active projection 105 just back of the plane of the projection 99 before mentioned, each of sa1d projections being substantially of a wldth equalling one-half the thickness of the cam 18. 'The bottom end of the lever 103 also carries a forwardlyy extending roller 106 which engages upon the rearwardly bent-over top flange 107 of the left hand end of a rocking lever 108. Said lever 1s pivoted at a point between its ends on a stud 109 fixed to the front face of the bracket 15 and the right hand end of said lever is connected to the top end of the detent plate actuating rod 79. A coiled spring 102 surrounds the stud 102 and is so connected to the bracket plate 15 and lever 103 as to normally .urge its top end toward the cam The operation of the machine is as follows Assume that the parts are all in their normal, at rest position as shown best in Figs. 1 and 3. Assume that there is a formed clip blank 83a in that pocket 58c of the anvil block adjacent the opening 23, through which one end of the webbing 112 is inserted into the head of the machine. Also assume that the stock strip 83 has been fed inwardly through the left hand side wall 22 of the head 16 and now extends across the opening 48 in the 4female` cutting die plate 46. l

The operator now inserts one end of the webbing 112 through the opening ,23a in the front plate until 1t engages with the clip blank 83 in the pocket 58c facing said opening (see Fig. 4) and actuates the clutch mechanism to connect the shaft 19 with the drivin element of the machine. The cam 18 wil rotate in a counter clockwise direction, the active portion 39a of the cam groove 39 forcing the roller 40 and the cutting die member 24 downwardly until the die 27 coacts with its opening 48 in the plate 46 and cuts a blank from the strip 83, said die 27 passing through said opening to deposit the cut blank upon the front and rear corrugated edges 51 of the plate 47 below the same, the die 27 and plate 47 cooperating to corrugate the parallel end edges of the cut clip blank. During this operation such chips or pieces as are formed in the cutting of the strip by the die 27 will fall into the chute-like opening 22a in the right hand side wall 22 of the casing to be discharged from the head 16. (See Fig. 7.)

After the flat clip blank has thus been cut and deposited upon the corrugated edges of the plate 47, the cutting die member 24 moves forwardly, withdrawing the cutting die and returning it to its normal position. when the active part 42a of the cam groove 42 approaches the associated roller 43 on the forming die member 25 and forces it downwardly. As said member moves downwardly, it will, through the spring 37, carry the indeuting or punching die 26 with it until the movement of the member 26 is momentarily arrested, as will later appear. As the point of momentary arrest of the indenting die is reached. before the downward movement of the forming member 25 has been completed, the final part of the movement of the member 25 will act to compress the spring 37 and put it under tension, the rod 35 being preferably so adjusted that its shoulder 38 will be engaged by the lug 32 on the member 25, when said member has completed its stroke.

In the downward movement of the member 25, its bottom end 25a will engage the flat clip blank and force it through the opening 50 in the plate 47, bending it as it passes through said opening and forcing it into the V-shaped forming-pocket 58c in the anvil block 55. As before mentioned, the outer margins of the pockets are defined and somewhat restricted vby the overhanging flanges 65-66 and in the final forming movement of the clip blank into said pocket, the two outer and now corrugated edges of said blank are forced beyond said flanges to engage behind them so as to become locked in'said pocket. As said clip blank is generally formed of thin aluminum, or of other thin metal which has little or no resiliency, the blank would, except for said overhanging flanges, tend to fall out of the pocket as the anvil is rotated to bring it into the position adjacent the opening 23a through which the end of the webbing 112 is inserted into the clip. Upon withdrawal of the forming die, the leaf springs 68 (see Figs. 4 and 13) which engage the free ends of the flanges 62 of the swinging wing part, will act to turn or swing said wing part about its end trunnions 61 and thus cause said wingipart to iyieldingly hold the formed clip blan in posltion in said pocket.v

As before stated, the indenting or punching die 26, being connected as described with the forming die, will move downwardly with the same. In the initial or first part of such movement, the points 29 will pass through the spaces 64 between the teeth 63 of the swinging win part, now adjacent the opening 23 in the ont plate 23, until the end 3()a of the block 30, between said teeth, engages the convex surfaces 67 of the teeth 63 of the Wing part 60. As the vertical plane of movement of the end 30a o the block 30 is spaced outwardly from the vertical plane of the axes of the trunnions 6l. of the wing part 60, further downward movement of the member 26 will result in the wing part 60 being swung upon its trunnions outWardly,-the openmg 23a being so formed at its sides that the anges 62 of said wing part may pass through the same. As said wing part is thus swung upon its trunnions, it will fold or bend the clip blank upon itself. The convex surfaces 67 of the teeth 63 of the wing part 60 are generated on a curve which Ywill retard the movement of the punching member 26 relatively to that of the forming member 25, before mentioned, so that the spring 37 is placed under tension until the end 30a of the tooth block.30 encounters and enters the concave parts-67a of the teeth 63 of the wing part 60,-When the retarding effect of said surfaces 67 is immediately released and the spring 37 will expand and drive or force the member 26 downward with a quick, impulsive stroke which forces the wing part through the final part of its movement and causes it to impart the final bending or folding over of the clip blank and at the same time driving the points 29 through the top side of the clip and forming triangular locking prongs which eectually secure the clip to the webbing.

The member 26 of course moves upwardly with the member 25 through the coacting shoulders 25"-26b (see Fig. 3).

At about this time the active peripheral cam parts 99 and 105 approach their coacting rollers 98 and 104, the roller 104 being engaged by its cam 105 to move it out- Wardly, thus actuating the lever 103 to depresslthe left hand end of the lever 108, lifting its right hand end which is connected to the .top end of the rod 79. As the rod is thus lifted, the detent plate 7 7 and its tooth 78 will be actuated to be withdrawn from the recess 72 to unlock the ratchet disc 71.

The active peripheral cam part 99 now engages the roller 98 and swings the lever 95 about its pivot, the bottom forked end 94 through the roller 93 moving, the block 88 on the guide `rods 87 toward the head 16. The roller 89 on the block 88 will act to clamp the stock strip 83 to the block so that the strip ris fed into the head and across the cutting die plate 46 a length sutlicient to rovide a. clip blank. As the block 88-v acting through one of the teeth 74 of the disc hub 73 to impart a like rotative movement to the disc 71. As said disc is fixed to the shaft 57, a similar movement is imparted thereto and to the rotary die or anvil block 55 to bring that pocket 58 in which the clip was just formed, into a position opposite the opening 23a ready for the insertion of another webbing end and bringing another pocket into position below the die pla-tes 46 and 47, readyxtor the next operation. lt is herein pointed out that as soon as the disc 71 and shaft 57 have been given their rotation, Athe tooth 78 of the detent plate enters into the notchv72 in the disc so that all parts fixed on the shaft 57 are locked in osition against any accidental rotation in either direction, thus insuring perfect registration or synchronism between the operating parts within the head 16.

As the active cam part' 99 passes the roller 98, the spring 96a will act to swing the lever 95Aback into its normal position, said lever acting in turn to slide the block` 88 on the rods 87 into its normal position, where it stops against the setfscrew 100. rlhe gripping roller 89 on the Vblock 88 will release it grip on the stop strip and the other gripping roller 85 will prevent the stock strip from ,moving outwardly as the said block 88 moves back to its original tion. As said block thus moves backsit will, through the screw 92 and slot 76, rotate the sleeveI 75 in a reverse direction, the spring pressed pin 7 5i clicking past the teeth 74, when all parts are in their normal position ready for the next cycle of operation, which will be the same as that heretofore described.A
